Multi functional roof fan manufacturer

DWT low noiseroof fanAdopting mold flow or centrifugal impeller, fan motor direct drive, anti-corrosion hood, metal or fiberglass wind duct base, it has the characteristics of corrosion resistance, light weight and high strength, smooth operation, simple maintenance, low noise, and excellent performance. It is widely used in various industries such as power generation, chemical industry, rubber, pharmaceuticals, food processing, metallurgy, and high-end civil buildings for ventilation and air exchange.

The DWT-I type adopts a wide blade, large chord length, spatially twisted inclined axial flow impeller, suitable for ventilation and air exchange in medium and low pressure, high flow situations.

The DWT-II model adopts optimized centrifugal impellers, which are suitable for exhaust and ventilation in high-pressure applications.

According to different usage environments and conveying media, impellers can be made of materials such as aluminum alloy, steel plate, engineering plastic, fiberglass, etc., and can be made into conventional, anti-corrosion, explosion-proof, and anti-corrosion explosion-proof types.

roof fanOptional accessories: Gravity check air valve (or electric type), anti bird (insect) net, maintenance switch, centralized control box and other accessories can be equipped as needed.

Characteristics
1. Multiple types and specifications, wide application range: The following types of fans can be selected according to the different requirements of air volume, air pressure, and noise in the usage scenario:
a、 Axial flow roof ventilation fan: code named DWT-I type, with the characteristics of large air volume and higher pressure than centrifugal fans. At the same time, according to user requirements, it can also be designed as a bidirectional rotating reversible type, with the characteristic of equivalent forward and reverse conditions.
b、 Centrifugal roof ventilation fan: code named DWT-II and DWT-III, suitable for situations with low air volume but high pressure requirements;
c、 Non motorized roof ventilation fan: code named DWT-IV type, suitable for steel structure roofs, is the first environmentally friendly fan product in the new century.
2. The high-efficiency and low-noise fan system adopts CAD series software, which has been developed through multi-objective optimization design. The 1200.1400.1500.1600.2000 and 2400mm fans in this series use the same diameter but different speeds and angles to change several quantities The method of wind pressure is used to meet the needs of different operating conditions, achieve fan system matching, and facilitate energy conservation and noise reduction;
3. Lightweight. High strength. Corrosion resistance; The fan impeller can be made of different materials according to the corrosiveness of the working air medium, including ABS (engineering plastic), FRP (fiberglass reinforced plastic), and aluminum alloy sheet. For centrifugal fans with high pressure requirements and high fan speeds, the impeller surface is specially galvanized and sprayed with plastic for corrosion resistance, which not only reduces the overall weight of the machine but also has good corrosion resistance;
4. Smooth operation and long lifespan; The rotational inertia of this fan is small, the dynamic balance accuracy is high, and the operation is smooth. The factory's internal control standards for various performance indicators are higher than the fan's unemployment standards, ensuring the stable operation of the fan;
5. Wide range of applications: the fan can be manufactured into explosion-proof and flame-retardant types according to the use requirements, and is suitable for anti-aging, pumping flammable, explosive and corrosive gases;
6. Beautiful appearance: The hood components of this fan are made of fiberglass, and the exterior is made of imported rubber coating resin film. The curved surface transition is soft, beautiful and generous, and practical; Steel wind caps can also be made according to user requirements and treated with galvanized spray coating (PVC);
7. Usage conditions: The temperature of the medium should not exceed 60 degrees Celsius, excessive viscous substances are not allowed in the gas, and the dust content should be less than 100mg/m. For situations where the medium temperature is high, our factory has high-temperature fan technology that can provide products for use.
8. This product has been tested and approved by the Zhejiang Provincial Product Technical Supervision Institute. The testing items include flame retardancy, conductivity, explosion resistance, wind resistance, etc. It is supervised by the Municipal Product Technical Supervision Bureau.
